TREX(`trt-engine-explorer`): fix matadata typo (breaks report_card) and compatibility between dtale and dash

I’m opening this issue in case it helps someone. If it’s useful, I’m happy to put together a PR.

Summary

• Fix the typo matadata → metadata in report_card.py.
• Update the dtale version higher than 3.17.0 in requirements-notebook.txt to restore compatibility with dash.

In detail

1) Typo: matadata

There are a few occurrences of matadata in trex/report_card.py.
This leads to a runtime error when calling report_card_draw_plan_graph_extended:

Example error stack (abbreviated):

.../trex/graphing.py:832 in to_dot
g = DotGraph(*args, **kwargs)
TypeError: DotGraph.__init__() got an unexpected keyword argument 'display_matadata'

Proposed fix
Rename all matadata to metadata across TREX code where used.

2) dtale ↔ dash compatibility

dtale imports dash.development.component_loader, which was removed in dash 3.0+.
With dash ≥ 3.0, this raises:

AttributeError: module 'dash.development' has no attribute 'component_loader'

Proposed fix
We can fix it in two ways
(1) Update the dtale version (fix https://github.com/man-group/dtale/issues/904)

# requirements-notebook.txt
dtale==3.18.2 # okay only if higher than 3.17.0

(2) Or pin dash to the last 2.x release in the notebook environment:

# requirements-notebook.txt
dash==2.18.2

This keeps dtale operational without changes.

Start with tools/experimental/trt-engine-explorer/trex/report_card.py and trace report_card_draw_plan_graph_extended through the reported DotGraph error. Then inspect tools/experimental/trt-engine-explorer/requirements-notebook.txt and verify the selected dtale and dash versions are compatible; done means the report-card path no longer raises the displayed errors.
